Today no picture, but a little Photoshop action, which I have recorded from a technique, which I have seen from Calvin Hollywood.
The action increases the details in the picture. So it is recommended to limit the intensity and the area where it will work.

To do so, run the action (attention: will work only on the actual layer, so in doubt merge all layers), adjust the intensity by increasing or reducing the value in the smart filter, then add a black mask to the details-group and demask all the areas you want to bolster up.
